Question

you can tell that this is an image of a dna nucleotide and not an rna nucleotide because you see a

sugar with two, and not three, oxygen atoms

phosphate group, not a uracil

uracil nitrogenous base, not a thymine nitrogenous base

thymine nitrogenous base, not a uracil nitrogenous base

double - stranded molecule, not a single - stranded molecule

Explanation:

• DNA nucleotides contain deoxyribose sugar (with one less oxygen compared to ribose in RNA) and thymine as a nitrogenous base. RNA has ribose sugar and uracil.
• The image shows a nucleotide with deoxyribose (sugar with two oxygen atoms in the ring structure relevant to the sugar - oxygen count comparison in nucleotides) and thymine (not uracil).

Answer:

sugar with two, and not three, oxygen atoms
